Learn More✈️New Airworthiness Directive for Piaggio Aviation Airplanes Issued
The FAA is superseding Airworthiness Directive (AD) 2023-25- 03, which applied to certain Piaggio Aviation S.p.A. (Piaggio) Model P- 180 airplanes. AD 2023-25-03 required a one-time detailed inspection of the horizontal stabilizer (HS) central box for corrosion; an assessment of the corrosion level; and depending on the determination, repetitive detailed inspections of the HS central box for corrosion and the internal composite structure for surface cracks, distortion, and damage; and repair or replacement of the HS assembly. Repair or replacement of the HS assembly was terminating action for the repetitive inspections. Since the FAA issued AD 2023-25-03, it was determined that AD 2023-25-03 imposed an unintended restriction that is not in the mandatory continuing airworthiness information (MCAI). This AD retains certain actions of AD-2023-25-03 and removes the unintended restriction. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is superseding Airworthiness Directive (AD) 2024-03- 07, which applied to all Deutsche Aircraft GmbH Model 328-100 and 328- 300 airplanes. AD 2024-03-07 required a one-time detailed inspection of each affected part, and applicable corrective actions. Since the FAA issued AD 2024-03-07, the FAA determined that repetitive inspections are necessary. This AD continues to require the actions in AD 2024-03- 07 and requires repetitive inspections of the affected part. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️Airworthiness Directive for Dassault Aviation FALCON 2000EX
The FAA is adopting a new airworthiness directive (AD) for certain Dassault Aviation Model FALCON 2000EX airplanes. This AD was prompted by reports of the incorrect installation of the very high frequency omnidirectional range and localizer (VOR/LOC) antenna coupler. This AD requires implementing an operational limitation for Category (CAT) II and CAT III approaches, inspecting the VOR/LOC antenna coupler, and reinstalling the VOR/LOC antenna coupler if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️FAA Final Rule AD 2025-15-07 for Boeing 747 Airworthiness
The FAA is superseding Airworthiness Directive (AD) 2025-01- 08, which applied to all The Boeing Company Model 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747-8F, and 747-8 series airplanes. AD 2025-01-08 required identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats and applicable on-condition actions for affected seats. AD 2025-01-08 also required a one-time detailed inspection and repetitive checks of the horizontal movement system (HMS) of the Captain's and First Officer's seats and applicable on-condition actions. Since the FAA issued AD 2025-01-08, the FAA determined that AD 2025-01-08 contains an error when providing conditions for taking credit using a previous revision of the service information. This AD requires the actions of AD 2025-01-08 and revises paragraph (j) of this AD to clarify which actions are not required. The FAA is issuing this AD to address the unsafe condition on these products.
Learn More✈️Proposed Directive for General Electric Engine Disk Replacements
The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) Model GE90-90B, GE90-94B, GE90-110B1, and GE90-115B engines. This proposed AD was prompted by a manufacturer investigation that revealed certain high-pressure turbine (HPT) stage 1 and HPT stage 2 disks were manufactured from powder metal material suspected to contain iron inclusion. This proposed AD would require replacement of affected HPT stage 1 and HPT stage 2 disks with parts eligible for installation. The FAA is proposing this AD to address the unsafe condition on these products.

Learn More⚛️Proposed Amendments to Spent Fuel Storage Regulations by NRC
The U.S. Nuclear Regulatory Commission (NRC) is proposing to amend its spent fuel storage regulations by revising the TN Americas LLC, NUHOMS[supreg] EOS Dry Spent Fuel Storage System listing within the "List of approved spent fuel storage casks" to include Amendment No. 4 to Certificate of Compliance No. 1042. Amendment No. 4 would change the certificate of compliance to incorporate a method to determine new loading patterns, introduce a steel plate composite option, introduce the use of MAVRIC software for a confirmatory run of the HSM-MX dose rates, make technical specification changes for consistency and terminology clarification, make various updated final safety analysis report editorial corrections for consistency and clarification, add measured exposures from past loading campaigns, allow use of a blended Portland cement, change the use of the MX- Loading Crane, and clarify the scenarios under which the maximum heat loads can be reduced.
Learn More⚛️NRC Denies Petition for Revised Design Basis Accident Dose Criteria
The U.S. Nuclear Regulatory Commission (NRC) is denying a petition for rulemaking, dated November 23, 2019, submitted by John G. Parillo. The petition requested that the NRC develop a rule that would allow nuclear power plant licensees to voluntarily adopt a revised accident dose acceptance criteria for the control room, exclusion area boundary, and the low population zone outer boundary. The petition further requested revisions to clarify footnotes discussing these dose acceptance criteria in the applicable regulations. The NRC docketed the petition on February 19, 2020, and assigned it Docket No. PRM-50-121. The NRC is denying the petition because the information presented does not support rulemaking and the proposed changes are not necessary to provide reasonable assurance of adequate protection of public health and safety.
